wire adapted to-be embeddedv in a tire orunoldecl-` product and constructed from an elongatedV straight-wire. Becauseoneof'the important-- uses:

cfmy wire struct-ure is in` tires, the use in that` respect isheredescribed'. Tire manufacturers havegdiscover'ed that tires would grip ice-coveredv surfacesmuch better in winter time if they had' manysmall members of' wireextending substarh. tially, vertically tothe surface ofthe. treadz However, it4 has 'always` beena problemi-to mold` the wires intire treads. and yetthave a small portion-` wea-r, that part of the zigzag wire extendable fromV the tread crsurface is worn throughand.

will provide many short members'orend portions ofA wire extendable outwardly from, the surface ofthe tread of the tire to engage ice-covered; roads orslippery pavement.v

After luy-corrugated zigzag wirelhasf been em:` bedded inthetread of a tire-for some time. `and the tire has-worn, the*` tops or*` the small. 'corru' gations close to; the surface of' the tire wearlhrough, thusprodu'cing what appears` tobe-'stv multitude of Ugfshaped wires embedded in thetiro with. the ends thereof extendable "beyondthe tread lsurface to engage ice or-pavement/I have also c discovered that by-.making the corrugations somewhat Ueshapedfwith relatively-long sides onA eachlcorrug'ation, ther small; pieces-o1?.l

wire remain embedded in the tire. When these many pieces of wire, which are preferably somewhat U-shaped, are other than circular, the small pieces of wire cannot rotate and thereby fall out of the tire. Many times it is preferable to construct the bends and the corrugations in a very sharp radiusfor in a somewhat V-shape instead of having them conform to the circular shape. I v

As shown in the drawings, the invention is directed to a corrugated zigzag Wire structure comprising an elongated strip for embedment ina 1y to the plane of the strip. The bends I2 may be characterized as the rst bends and integrall l ly join the zigs and zags in series ina zigzag fashion laterally to theplane of the strip and space the zigs from the zags in a direction longitudinally of thestrip. Each zig and zag co'nsists of a series of intermediate portions I5, each extending transverselyto the planeof lthe strip. The intermediate portions are preferably straight. The ends of the intermediate portions I5 are integrally joinedin series by the second bends I6 in a corrugated fashion transversely to the plane of the strip.` The second bends I6 space the lintermediate-'portions I5apart from eachv other in a, direction laterally to the plane of the strip. As shown in the drawing, the intermediate portions which are integrally joined by the secondI bends produce a middle corrugation I3 and side corrugations I4.

The joined end portions ofthe zigsl and zags constitute side portions I 'I of the strip and extend transversely to the plane of the strip. The side portions I 1 are substantially the same length as the intermediate portions I 5. The intermediate portions I5 are spaced apart in a direction laterally to the plane of the strip at distances less than the transverse distance between the successive bends.

'Although the invention has been described in its preferred form with a certain degree of particularity, it is understoodthat therpresent disclosure of the `preferred form has been made only by Way of example and that numerous changes in the-details of construction and the combinationand arrangement of parts may be resorted to kWithout departing from-the spirit and the scope of the invention as hereinafter claimed.
